the piet-ee @e l pose nfl all this will fully appear in the description of operation of my improved apparatus.

At one side o'f the tank is the track 41 upon which travel the trucks 42. These trucks 42 have the pivotally mounted cradles 43 to receive the end of the cylinder as itis lowered in vertical position, and as said truck is moved outwardly to lower the cylin'der the cradles'tilt automatically according to the inclination of the cylinder until the cylinder is brought into -a horizontal position with its opposite end vresting onl a truck having a different form of cradle44 to support the upper end of the cylinder. To provide for the swinging of the'arms 14 I provide the cables 53 which extend down into convenient position to be reached by an operator standing on the floor below.

I also provide mechanism for locking the arms in position and said locks in the form illustrated consist of the latch 4G pivotally connected at 47 to the arm. A pin 48 is' connected with. said arm, said pin passing up through an opening 49 in said arm anda spring 50 surrounding said pin, said spring being interposed between said arm and the nut 51 on said pin. The outer end of the 4latch 46 is adapted to engage notches or seats, v52 formed in the cross head 7, and

when said latch engages one'of said seats the arm is locked in position. In order to release the arm I provide the chain 53 connected totheeyelet 54 on the pin 48, and by drawing down on said chain the latch is releasedfrom its recess and the arm can' then be moved into the desired position. As the arm is moved .aroundit willl register with one of the seats52'and due to the action of -the spring the latch-'will spring into locking position and lock. the ar-m automatically. v

is lowered in order to bring the arms 14 .to their lowermost position indicated' in dotted 'lines Fig. 1 which lowers the bait down into the glass in the tank 3, the rings 5 having been previously lowered. In order to lift the arms 'and the bait carried thereby, the valvev 2Q is opened and theairlpressure admitted to the upper end of the 'tank 26.

andaccordingly 1n weight, greater lifting `power is required and this is pbtained by relieving proportionately the resistance to the upward movement of the piston '24 by allowing thewater to escape in greater quan- 6e times from the space above the piston in the In the drawing of cylinders the cross head" cylinder 22. This is provided for by the controller 33, for as the water is forced out through the pipe 32 and up into the controller, the piston 34 of the controller .is raised and as said piston is -raised through the lever connections described, the valve 40 is opened to greater extent so that the pressure applied to the lower` end of the piston 24 of the cylinder 22 moves the arms up at a uniform speed and the cylinder is drawn without any sudden or abrupt increasg-in .speed of drawing7 and consequently :a

greater uniformity of diameter and thick--4 ness of glass -is possible.

As hereinbefore referred to, the air admittedv through the pipe 17 'to the cylinder during the drawing operation is previously heated or expanded, so that the pulsations `in the drawing operationsare avoided, all as fully set forth in the applicationl of even' date herewith and above referred to. 4' When the cylinders have been drawn to their full length, the rings 5 are lifted whereupon the heat of the furnace melts off the glass at the' lower end of the cylinder and disconnects it from the glass at the lower endof the cylinder and disconnects-it from the glass in the tank, whereupon the cylinders are raised to a further extent where the lower end of the .cylinders clears thevtopend of the tank, whereupon by means of the cables 45 the latches 46 having been released, the arms 14. are swung around into thel position indicated in dott-ed lines Fig. 1 or laterally lfor their entirel length, so as to bring them out beyond the tank in position to be lowered. In lowering one o`f the trucks-42 of the pistonv 34 of the controller, as well as thev piston24 of the cylinder 22. The cylinder is lowered gradually.- and as'it is lowered it comes into engagement with the cradle 43 whereupon the truck is moved outwardly, the cylinder being brought to a i gradually 'inclined position `until the cyin.- der is finally. lowered to a horizontal position with its .uppercnd resting on one of the trucks carrying the cr adle 44, as clearly indicated in Fig. 4 of the drawing. When in. this position, the cylinder is` separated from the blow pipe and is then 4in position' to be cut up into suitable lengths i,

In Fig. 9 I havdgi'llustrated a modified form of -my inventi n in which`the air heated electrically instead of by a ygas burner before being admitted to the cylinder, and to this end .I provide ,the heating chamber .56 with the heat-ing coils 57 therein. The air- 1s supplied to the heater by the pipe 5 8. The

air passes from the heater by the pipe 59 and this pipe is controlledv by the valve 60.

musees The air passes into the liftin c linder 61 which has the piston 62 an t e hollow piston rod 63. In this case the air not only lifts the cylinder in the drawing operation, but a portion ofthe air passing through the hollow piston rod enters the` cylinder through a flexible pipe connection.
